[TYPO3-templavoila] How to test an empty container / section with TypoScript?

[Olivier Schopfer]

Hi there,

Does anybody know a way to test if a section contains sub-items or not?

I want to be able to hide the following list of links in case it's 
empty. I suppose that one could achieve that with a .if TypoScript 
condition. But how to access the subfields? And how to change the 
overall wrap of the section (I've tried to put some Typoscript at the 
level of the container, but it doesn't seem to work).

Thanks for any help.
